CRINGLE.

SPECIFICATION forming part of Letters Patent No. 310,414, dated January6,1885.

Application filed May 8, 1884. (No model.)

To all whom it may concern.-

Be it known that I, J OIIN W. GREENE, a citizen of the United States,and a resident of Deer Isle, in the county of Hancock and State ofMaine, have invented certain new and useful Improvements in Grin glesand I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification,and in which Figure l is'a perspective view of my improved cringle andclew, applied to the edge of a sail. Fig. 3 is a cross-section of thesame, and Fig. 3is a perspective view of the two halves of the cringleseparated.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to cringles or elews for the attachment orpassage of ropes or reefs in the edges of sails, and it consists in theimproved construction and combination of parts of a cringle made ofmalleable metal in two parts, connected to clamp the sail by means ofrivets and metallic bushings inserted through perforations inthe twoparts, as hereinafter more fully described and claimed.

Gringles as now in general use consist of a piece of rope passed arounda grommet or thim ble bearing with one side against the outer side ofthe boltrope of the sail and through eyelets in the sail, one piece ofrope and one grommet being placed above the other; and

this manner of forming the cringle has been,

proven to have many drawbacks, in the shape of the rope in the eyeletstearing the sail, and by all the weight and strain of the cringle beingoutside the edge of the sail and its boltrope; and to obviate thesedrawbacksl con struct the cringle as I will now proceed to describe.

In the accompanying drawings, the letter Aindicates a portion of theleech of a sail; and B the bolt-rope, which is secured in the usualmanner in the edge of the sail.

(J-O indicate two pieces of malleable metal having flat meetingsurfaces, having a number of rivet-holes, D, near their edges and intheir middle, and having longitudinal grooves E in the middle of theirmeeting surfaces,

which grooves likewise have rivet-holes, which grooves serve to clampthe bolt-rope of the sail, the two halves of the cringle clamping thesail. The portion G within the bolt-rope has a perforation or clew-eye,H, which is provided with a metallic bushing or grommet, I, and theouter portion, J, outside the bolt-rope has two perforations, K, formingthe cringle, through which the reef -ta-ckle passes, one above theother, which may be provided with bushings L, which bushings or grommetsserve, together with the rivets M, which pass through the rivet-holes inthe grooves and near the edges of the portions of the cringle,

to secure the two halves of the cringle together, clamping the sail andbolt-rope. In this manner it will be seen that the strain upon thecringle will be divided between the portion of the sail which is clampedby the eringle and the bolt-rope, and that there will not be the straintending to sever the bolt-rope from the sail as in the first-describedold style of cringle, the weight of the portion of the cringle withinthe bolt-rope balancing the weight of the portion outside the bolt-rope.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. A cringle consisting of twohalves having corresponding longitudinal grooves upon their meetingsides, having corresponding cleW-eyes in their inner portions, havingcorresponding or registering cringle-eyes in their outer portions, andhaving rivet-holes, as an article of manufacture.

2. The combination of the sail, the bolt-rope, the cringle-halves havingregisteringgrooves for the bolt-rope upon their meeting sides, havingregistering clew-eyes in their inner portions and registeringcringle-eyes in their outer portions, and having registering rivetholes,the rivets, and the bushings inserted in the eyes, as and for thepurpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaifixed my signature in presence of two witnesses.

JOHN WINFIELD GREENE.
